MPRQVEMIENTIN PACKING-CASE PGR SAWS.

The Schedule referred to in lthese LettersPatent and making part of the same I, HENRY Drssron, of Philadelphia, county ofy Philadelphia, State of Pennsylvania, have invented a Packing-Ring for Circular-saw'Blade's, of which the following isa specification.

Nature and Objects of helm-eration. My invention consists of'fa wooden ring or rings ara circular saw,

and to inclose theteeth of,` the same, substantially as described hereafter.

The objects of myinvention are todispensc with the cumbrouspacking-boxes, in which circularj saw bladeshave hitherto been transported, *to-facili? tate "the removal of the blade-from place to place, tof eieetually protect the `teeth from injury, and 'toj afibrd facilities for, and prevent the danger of remov `ing the blade from, andjreadjustingit in its bearings.

p Description of the `21cco'mpanyt'ng Draw/ing. Figure 1 is a side view `ot' a circular saw-blade with' :my improved packing-ring.

Figure 2, an edge view of,` the ring n Figure 3 the same partly insection; and

Figure 4, a side View of` the saw-blade, with 'part of the packing-ring opened, and shown by dotted lines. General Description.. In packing circular-saw blades for transportation,

" 'f itxis usual to employ eumbrous and costly boxesy 1argeenoughtocontain the blades, .these boxes being discarded as waste lumber when the saws have reached their destination.` u

"In place of such packing-boxes I use for each blade what I term a fpacking-ringwhich not only takes the place of the more cumbrous box, but can be usedat any time for attachment'to the blade when the latter has'to be removed from, and replaced in its bearings.

e *I will now proceed to describe onemode of constructing my improved packing-ring, reference being had to the accompanying drawing.

A is the blade o f a circular saw, to each side of Ywhich is tted a vwooden ring,'B, the ring being in such a position, and of such dimensions, as to more thaninclose the teeth of Athe blade, (see iig. 4.) Each ring is, `in the present instance, eompbsed of two segments, a and a', the segments of 'the -twol rings `being connected together by a hinge, b, in such a mannerthat the segments, of one ring can be opened without disturbing those of the" other. Thus the seg- `ments of the ringB are shown as being opened infig. 45 `While the vsegments of. "the opposite ring B' are closed, and may be `retainedin a closed condition by an ordinary hook and staple, as 1sho'wnin iig, 1, or by any other suitable fastening.

There are, in the opposite rings, any desired number of yholes for receiving bolts, x, there being, in the' present instance, six bolts. y 'v After one of the rings hasv been opened sufliciently' to permit the adjustment of the blade A into the closed` ring, as shown in tig. 4, the opening is closed, its segments connected together at their outer ends, and the bolts x are then passed through the holes in the opposite rings, their nuts tightened, andthe blade is ef'ectually gripped between the two rings, the latter, in fact, for the time being, forminga part ot' the blade, which is now ready for transportationV It will be seen that the". bolts are so arranged as regards number and location, that each bolt occupies :tz-position in the recess in Ifront of one of the teeth.

' For circular saws with inserted teeth, the boltsv f mustfbe in contact with the solid part of the saw. v .The advantages of my'inrention may be enumeraand describedas follows:

Firstly, the packing-ring ig much lighter than an `ordinary packing-box, at the same time `it eifectually protects the saw-blade at a `point where protection is most needed. n

Secondly, the saw-blade,l packed according to my improvement, can be readily rolled from place to place, in thesame manner as a cart-wheel, without injuring the teeth, as the the ring 4projects beyond the ends ottheteeth.

Thirdly, the ring, with its bolts,fafi`ords a medi-v yum by which the saw-blade can be raised and lowered, the` hoisting-tackle being-'connected direetlyto the ring, e y

`Fonrthly, the ring can, at any time, be readjusted to a saw-blade, when the latter has to be removed from or restored to its bearings, the ring .being used as a medium for the. removal, replacing, and handling of theblade. p This is an important advantage, as the` handling of a circular-sawblade in fitting it to, or detachingit from, its bearings, is amatter involving both great labor and considerable danger, which can be obviatecl bythe use 'of the ring.

Ordinary bent segments, such as are used for making the rims of wagon-wheels, may be employed in manufacturing packing-rings, and these rings maybe composed of more than two segments.

It is not necessary, in carrying out my invention, that the rings Vshould be hinged together, as shown and described, for each ring may be continuous iri-V stead of being separable, and the saw-blade may be gripped between these rings by bolts.

For saws of smaller site, the ring may consister two simple segments having internal grooves for it-V ting tothe blade, the segments being secured byany suitable fastenings', after adjustment.

My invention, therefore, is not limited to the precise In testimony whereof I have signed my name to this mode described above, and illustrated in the drawing, specification in the presence of two subscribing witof constructing the ring. f nesses.
